Detection of Mouse TCF7/TCF1 by Western Blot. Western blot shows lysates of EL‑4 mouse lymphoblast cell line and mouse thymus tissue. PVDF membrane was probed with 1 µg/mL of Rat Anti-Mouse TCF7/TCF1 Monoclonal Antibody (Catalog # MAB8224) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). Specific bands were detected for TCF7/TCF1 at approximately 30-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of TCF7/TCF1 in EL‑4 Mouse Cell Line by Flow Cytometry. EL‑4 mouse lymphoblast cell line was stained with Rat Anti-Mouse TCF7/TCF1 Monoclonal Antibody (Catalog # MAB8224, filled histogram) or isotype control antibody (Catalog # MAB0061, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0113). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

TCF7 (Transcription factor 7), also called TCF1 (T cell factor 1) is a member of the lymphoid enhancer binding factor family of proteins that is expressed in thymocytes and mature T cells. In resting cells, TCF family members are transcriptional repressors, and are 25‑32 kDa in size. Following activation, the large TCF7/TCF1 isoform (isoform 2, chosen as 'canonical') predominates (419 amino acids, 42‑50 kDa), and serves a transcriptional activator function. The use of an alternate start site at Met116 seems to characterize repressor isoforms. Within aa 61-116 of the large form, mouse TCF7/TCF1 shares 77% aa sequence identity with human TCF7/TCF1.
